I have found a lot of different numbers and tests over the years...But I would like to know what you know Well I will be also happy with specifications for challenger 440+6 and automatic 440+6 cudas. If you have any of these cars at home...Would you do me a favor and take it to 60 and 100 mph and tell me the time you needed. Maybe you have some tests from old magazines and so on...

Here's a road test from SPORTS CAR GRAPHIC magazine, November 1969, for the 440-4bbl Challenger. I'll look in my old magazines to see if there's any for the 6 bbl version. I hope this helps in some way.

Does the 3.54 pull harder in the higher mph ranges where the sweet spot of the motor is at, whereas the 4.10 is stronger off line?

Maybe on the quater mile track the 3.54 4 speed might won because of its better top end and extra 15 hp...But the 4.10 has quick launch, automatic shifts faster and 15 hp don't actually help a lot. We just have to try it but I would bet on 4.10 automatic.

Thank you guys for your answers ...BGfish I already have that test but thanks anyway . The normal 440 version was a lot slower than a six-pack car for about a second right? The six carbs could easily compete with hemi while the 4 barrel 440 can't keep up with its big brother. The challenger is also heavier than a cuda so cuda is faster. right? .

I don't know but for me 14.4 seconds on the 1/4 mile it is slow. The AAR can do that. The big 7.2 litre engine with 390Hp in a car with 3720 pounds and 3.54 final drive ratio should perform better. What do you think? Dodge SuperBee six-pack does it in 13.8 seconds and it is much heavier than a cuda...

You have to take these old stats with a grain of salt ... those tires were so poor at harnessing even the small block horsepower that it was a joke to go 0 - anything in a big block. Back in the day, we raced from a 20 - 30 mph roll. I may get a chance to take mine out today. If so, I'll do a 60 - 100 run for you which will give you a ballpark number. I sacrifice a measure of performance at my 2000+ ft elevation, but again, it'll be close.
